The usage and operation of the horizontal blind 10 configured in this way will be described. When blocking the light entering from the window in the rectangular window frame 16, first, the elevating and tilting operation member 34 of the horizontal blind 10 is operated to simultaneously operate the slats 13a and 14a of the two sets of slats 13 and 14. It stands up and lowers the lower surfaces of the two sets of bottom rails 27 and 28 to the upper surface of the lower frame portion (not shown) of the window frame 16. At this time, the slats 13a and 14a are in an upright state, and the upright states (in FIG. 1A, the slats 13a and 14a are in a horizontal state, but these slats 13a and 14a are in an upright state. And in FIG. 4A), when the expansion / contraction operation member 43 is operated, the pulley rotates and the expansion / contraction drive shaft 37 rotates in the direction of the solid arrow in FIG. 5B, and the expansion / contraction drive shaft 37 is fitted. The three male screw members 38 on the right side are rotated in the same direction as the expansion / contraction drive shaft 37 (the direction of the solid arrow in FIG. 5 (b)), and the three female screw portions 41 on the right side are shown in FIG. 5 (b). Move in the direction of the broken arrow, that is, to the right. At the same time, the three male screw members 39 on the left side fitted with the telescopic drive shaft 37 rotate in the same direction as the telescopic drive shaft 37 (in the direction of the solid arrow in FIG. 6B), and the three female threads on the left side. The portion 42 moves in the direction of the broken line arrow in FIG. 6 (b), that is, to the left. As a result, the non-polymerizing take-up drum 19 and the non-polymerizing tilting drum attached to the two non-polymerizing drum holders 18 on the right side, and the polymerization tilting drum attached to the one polymerization drum holder on the right side. As the polymer moves to the right, the slat group 13 on the right side and the bottom rail 27 on the right side move to the right and approach the inner surface of the right frame portion (not shown) of the window frame 16 at the same time. Since the non-polymerizing take-up drum 19 and the non-polymerizing tilting drum attached to the non-polymerizing drum holder 18 move to the left, the left slat group 14 and the left bottom rail 28 move to the left and the window. It approaches the inner surface of the left frame portion (not shown) of the frame 16. As a result, the polymerization lengths of the two adjacent slat groups 13 and 14 become smaller, and the slat group unit 12 extends in the longitudinal direction (although in FIG. 1B, the slat groups 13a and 14a are in a horizontal state. , The state in which these slats 13a and 14a are erected, and FIG. 4 (b).

At this time, each of the slat 13a of the slat group 13 on the right side of the two sets of slat groups 13 and 14 adjacent to each other in the polymerization section 33 is held by one set of the polymerization ladder code 31, that is, they are adjacent to each other in the polymerization section 33. Since the polymerization horizontal cord 31b was interposed between the slat groups 13a and 14a that were in contact with each other or adjacent to each other among the two sets of slat groups 13 and 14, the polymerization horizontal cord 31b was interposed when the slat group unit 12 was expanded and contracted in the longitudinal direction. It is possible to suppress the sliding resistance between the 31b and the slats 13a and 14a at the same time and suppress the adhesion between the slats 13a and 14a at the polymerization portion 33 at the time of dew condensation. That is, when the slat group unit 12 expands and contracts in the longitudinal direction, the sliding resistance generated between the two adjacent slat groups 13 and 14 and the polymerization horizontal cord 31b is the slat group 13 and 14 and the above. It is suppressed by the arrangement with the horizontal string 31b for polymerization. Specifically, although the load of each slat 13a of the right slat group 13 is applied to the polymerization horizontal cord 31b, the load of each slat 14a of the left slat group 14 is not applied, so that the right slat group 13 and the right slat group 13 and The left slat group 14 moves smoothly, respectively, and the followability of the right slat group 13 and the left slat group 14 to the expansion / contraction motion can be improved. As a result, both ends of the two sets of slat groups 13 and 14 in the longitudinal direction can be maintained in the vertical direction during and after the expansion and contraction, and the regularity of the slat groups 13 and 14 is prevented from being disturbed. can. Further, even if the pair of polymerization vertical strings 31a and 31a are violent when the two sets of slat groups 13 and 14 are raised and folded at the same time, the slat 13a of each slat group 13 on the right side of the polymerization horizontal string 31b is attached to the polymerization horizontal string 31b. Since the load is applied, the violence of the pair of vertical strings 31a and 31a for polymerization is suppressed. Therefore, it is possible to prevent the pair of polymerization vertical strings 31a and 31a from loosening regularly and the loosening states of the pair of polymerization vertical strings 31a and 31a from becoming uneven.

Further, since the slats 13a and 14a of the two sets of slats 13 and 14 are in an upright state and the slats group unit 12 extends in the longitudinal direction, the total amount of gaps where light leakage occurs changes, and the slats Almost all of the rectangular window frame 16 is covered by the group unit 12. Therefore, it is possible to prevent the gap between the adjacent slat groups 13 and 14 of the slat group unit 12 and the light leakage from the outer surface of the slat group unit 12.

9 to 11 show a second embodiment of the present invention. In FIGS. 9 to 11, the same reference numerals as those in FIGS. 1 to 3 indicate the same parts. In this embodiment, one set of polymerization ladder cords 113 is provided with a pair of polymerization vertical strings 113a, 113a arranged in front of and behind two sets of slat groups 13, 14 adjacent to each other in the polymerization section 33. It has a pair of polymerization horizontal cords 113b and 113b erected one by one at intervals in the longitudinal direction on the polymerization vertical cords 113a and 113a. The pair of polymerization vertical strings 113a, 113a are arranged so as to extend vertically along the leading edge and the trailing edge of the slats 13a, 14a of the two adjacent slats groups 13, 14. Further, one end of the pair of polymerization horizontal cords 113b, 113b is fixed to the indoor side polymerization vertical cord 113a of the pair of polymerization vertical cords 113a, 113a, and the other end of the pair of polymerization horizontal cords 113b, 113b is fixed. Of the pair of polymerization vertical strings 113a and 113a, they are fixed to the polymerization vertical string 113a on the window side. Then, in this embodiment, the pair of polymerization horizontal cords 113b and 113b sandwich and hold each slat 13a of the slat group 13 on the right side of the two adjacent slat groups 13 and 14 from the upper surface and the lower surface thereof. It is configured as follows. Further, each slat 14a of the left slat group 14 is located directly below the lower polymerization tie string 113b of the pair of polymerization tie strings 113b, 113b that sandwich each slat 13a of the right slat group 13. It is composed of. In addition, although it is described in FIG. 9 that the two sets of slat groups 13 and 14 are extended in the horizontal state, in reality, the two sets of slat groups 13 and 14 are extended in the upright state. There is.
Other than the above, the configuration is the same as that of the first embodiment.

The usage and operation of the horizontal blind 100 configured in this way will be described. In the case of shielding the light entering from the window in the rectangular window frame 16, first, as in the first embodiment, the operation member for raising and lowering the horizontal blind is operated to operate the two sets of slats 13, 14 The slats 13a and 14a of the above are simultaneously erected, and the lower surfaces of the two sets of bottom rails are lowered to the upper surface of the lower frame portion of the window frame 16. At this time, in the state where the slats 13a and 14a are upright (in the state where the slats 13a and 14a are in the horizontal state in FIG. 9A, but these slats 13a and 14a are upright), the expansion / contraction operation member is used. When operated, the non-polymerizing take-up drum and the non-polymerizing tilting drum attached to the two non-polymerizing drum holders on the right side and the polymerization tilting drum attached to the one polymerization drum holder on the right side. Since it moves to the right, the slat group 13 on the right side and the bottom rail on the right side move to the right and approach the inner surface of the right frame of the window frame, and at the same time, they are attached to the two non-polymerizing drum holders on the left side. Since the non-polymerizing take-up drum and the non-polymerizing tilting drum move to the left, the left slat group 14 and the left bottom rail move to the left and approach the inner surface of the left frame portion of the window frame. As a result, the polymerization lengths of the two adjacent slat groups 13 and 14 become smaller, and the slat group unit 12 extends in the longitudinal direction (although in FIG. 9B, the slat groups 13a and 14a are in a horizontal state. , These slats 13a, 14a are upright).

At this time, each slat 13a of the right slat group 13 is sandwiched by a pair of polymerization horizontal cords 113b, 113b of the polymerization ladder code 113, and each slat 14a of the left slat group 14 is each of the right slat group 13. Since it is located directly below the lower polymerization horizontal cord 113b of the pair of polymerization horizontal cords 113b and 113b that sandwich the slats 13a, the pair of polymerization horizontal cords when the slat group unit 12 expands and contracts in the longitudinal direction. It is possible to suppress the sliding resistance between the 113b and 113b and the slats 13a and 14a at the same time and suppress the adhesion between the slats 13a and 14a at the polymerization portion 33 at the time of dew condensation. That is, when the slat group unit 12 expands and contracts in the longitudinal direction, the sliding resistance generated between the two adjacent slat groups 13 and 14 and the pair of polymerization horizontal cords 113b and 113b is the slat group 13. , 14 and the pair of polymerization horizontal cords 113b, 113b are arranged to be suppressed. Specifically, of the pair of polymerization horizontal cords 113b and 113b, the lower polymerization horizontal cord 113b is loaded with the slats 13a of the right slat group 13, but each slat of the left slat group 14 is applied. Since the load of 14a is not applied, the slat group 13 on the right side and the slat group 14 on the left side move smoothly, respectively, and the followability of the slat group 13 on the right side and the slat group 14 on the left side can be improved. As a result, both ends of the two adjacent slat groups 13 and 14 in the longitudinal direction can be maintained in the vertical direction during and after the expansion and contraction, and the regularity of the two adjacent slat groups 13 and 14 can be maintained. Can be prevented from being disturbed. Further, even if the pair of polymerization vertical strings 113a and 113a are violent when the two adjacent sets of slat groups 13 and 14 are raised and folded at the same time, the pair of polymerization horizontal strings 113b and 113b are on the right side of the slat group. By sandwiching each of the slat 13a of 13, the load of each slat 13a of the slat group 13 on the right side is applied to the lower polymerization horizontal cord 113b of the pair of polymerization horizontal cords 113b and 113b. The rampage of the polymerization vertical strings 113a and 113a is suppressed. As a result, it is possible to prevent the pair of polymerization vertical strings 113a and 113a from loosening regularly and the loosening states of the pair of polymerization vertical strings 113a and 113a from becoming uneven.

Further, since the slats 13a and 14a of the two sets of slats 13 and 14 are in an upright state and the slats unit 12 extends in the longitudinal direction, light leakage occurs as in the first embodiment. The total amount of gaps changes, and the slat group unit 12 covers almost all of the rectangular window frame 16. Therefore, it is possible to prevent the gap between the adjacent slat groups 13 and 14 of the slat group unit 12 and the light leakage from the outer surface of the slat group unit 12.
